New build, new concerns (can't test for 2 weeks) -

[MiRai]

I need some advice on decent PSU brands and what would be required to power this machine, I overclock.

Anything with something like 850W. Corsair, Seasonic, and EVGA seem to all make/sell some pretty decent PSUs.

Don't have a case yet, since the GPU has that AIO cooling setup, I am still looking for something with enough fan slots to swap around (any ideas?).

I didn't want to ignore the question, but I don't have an answer. This is generally something you're going to need to look for yourself since cases are pretty much personal preference.

The real concern, that I didn't pay much attention to in my haste was the VRAM. I'm going to only play 10 accounts, will the Fury X be ok? I've tried searching but i'm not getting the best results (or my google skills are weak).

This album shows some single player VRAM usage numbers at the Alliance garrison in Shadowmoon Valley. You can subtract ~430MB off of those numbers since my idle desktop eats up that much before loading up the game client.

They're all 2560x1440 (based off of the monitor you've purchased) and they're without any anti-aliasing. From the looks of it, and assuming you want to run a resolution somewhere in the ballpark of 2560x1440, you may have to mix and match your APIs since DX11 on 10 clients is likely going to use over 4GB of VRAM.

And yes, in that album, DX9 on Ultra was running terrible. I do suggest using DX11 these days whenever possible since you're bound to get better framerates, and you may have to end up disabling SSAO altogether since it tends to eat a lot of VRAM and GPU.

I should buy another monitor too right? I have my old S27A950D which is only 1080p, mixing resolutions doesn't work so well with mouse repeater... oor does it? :P

Mixing resolutions doesn't always work out depending on the layout you want to use, but you can generally make it work.

Finally loading times! Should I buy another SSD and RAID 0?

Probably not worth it since SSDs are fast enough on their own, but if you were going to buy another SSD then it'd be useful as a drive just for the OS or just for games (however you want to look at it).
